You've deployed a microservice called myapp1 to a Google Kubernetes Engine cluster using the YAML file specified below:

You need to refactor this configuration so that the database password is not stored in plain text. You want to follow Google-recommended practices. What should you do?

• A.Store the database password inside a ConfigMap object. Modify the YAML file to populate the DB_PASSWORD environment variable from the ConfigMap.
• B.Store the database password inside the Docker image of the container, not in the YAML file.
• C.Store the database password inside a Secret object. Modify the YAML file to populate the DB_PASSWORD environment variable from the Secret.
• D.Store the database password in a file inside a Kubernetes persistent volume, and use a persistent volume claim to mount the volume to the container.

• B.Create a VerticalPodAutscaler for those workloads.
• C.Create a node pool with preemptible VMs and GPUs attached to those VMs.
• D.Create a node pool of instances with GPUs, and enable autoscaling on this node pool with a minimum size of 1.
